Re: [Jmol-users] Class Not Found Exception while using the applet tag

Harini. You present yourself a challenge, since different browsers
require different configurations of these tags. Most likely some user
platforms will not load your page. But if you feel you really cannot use
Jmol.js, then at least use it once and have it display the proper tag
for you. Just use this once to see what it gives, then cut and paste::
Just from you hard drive -- just to see what the code is supposed to
look like:
<script src=Jmol.js></script>
<script>
jmolSetDocument(0)
s = jmolApplet(400)
document.write("<pre>"+s.replace(/\</g, "<")+"</pre>")
</script>
or, if you wish to force the <applet> tag instead of <object>:
<script src=Jmol.js></script>
<script>
jmolInitialize(".")
_jmol.useIEObject = false;
_jmol.useHtml4Object = false;
jmolSetDocument(0)
s = jmolApplet(400)
document.write("<pre>"+s.replace(/\</g, "<")+"</pre>")
</script>

With forcing, Jmol.js will produce this:
<applet name='jmolApplet0' id='jmolApplet0' code='JmolApplet' archive='JmolApplet0.jar' codebase='.'
width='400' height='400' mayscript='true'>
<param name='progressbar' value='true' />
<param name='progresscolor' value='blue' />
<param name='boxbgcolor' value='black' />
<param name='boxfgcolor' value='white' />
<param name='boxmessage' value='Downloading JmolApplet ...' />
<param name='script' value='select *' />
<table bgcolor='yellow'><tr><td align='center' valign='middle' width='400' height='400' >
You do not have the<br />
Java Runtime Environment<br />
installed for applet support.<br />
Visit <a href='http://www.java.com'>www.java.com</a></td></tr></table></applet>
